(Grammar) UNDER THE rRovIsIoNs or THE' Aer-or MARCH 3,1883, assur. Incas.)

The invention described herein may be used by the Government, or any of its officers or en'iployees in prosecution of workjfor the Government, or by any other person in the United States, without payment to vme of any royalty thereon, in accordance -with the act of March 3, 1883.

The subject of this invention is a mount for guns.

Infantry accompanying guns of l37 m/m caliber are moved either by hand or wheeled transport and because of their tactical employment they must be capable of rapid adjustment to the traveling and firing position. In the present invention the provision for this rapid adjustment is associated with the traversing mechanism so that the vgun may be quickly trained on a new target. j

1V ith the foregoing and other objects in view, my invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment `of the invention herein disclosed may be madey within the scope of what is claimed'without departing from the spirit of the invention.

A practical embodiment of the invention is illustrated in the accompanying drawings, wherein:

Fig. 1 is a view in side elevation, parts broken away, showing the mount in the liring position;

Fig. 2 is a detail sectional view through the pintle assembly;

Fig. 3 is a detail line 3 3 of Fig. l;

F ig. si is a detail sectional view on the line 1 4 of Fig. 2.

Referring to the drawings byrnumerals of reference The mount is of a standard type whichV in general comprises a tripod having a forwardly extending stud 6 to provide for its suspension from the axle 7 of a wheeled unit. The pintle 8 is in the form of a yoke, the upper end 9 being fitted to receive the cradle trunnions and thelower portionpivotally carrying a pair of trails 10-10, a front leg 11, and a Y-frame 12. This frame carries the elevating mechanism 13 and terminates at its rear extremity in a forli 14 which engages vertical studs 15a on a housing 15 freely slidable on a traversing screw 16. Mounted in the housing 15 is a plunger sectional view on the 17,L havinga handle 18 on its outer endfand `having its inner endlQshaped to engagea thread. 2O of ka wide pitch in' thetraversing screw. l/Vith the'k plunger-engaged the pivoted frame 12 and elevating' mechanism 13 `to which the breech end ofthegun is secured will Vbe firmly loeked'thereby' lmaintaining the gun in its position ofazimuth while with the vplunger disengagedthejframe and gun may be freely swung about the pintlen,A

1n order that the traversingl screw may be rotatedl to 'cooperate with the locking plunger in effectingminor adjustments a handwheel 21 is fixed to the screw adjacent one of the trails. The hand-wheel anda headed end 16 on the screw serve `to prevent lateral displacement of the screw with respect to a coupling 22 connecting it `pivotally to the left hand trail. The opposite coupling 23 by engaging only the headed end 16 of the screw limits the extension of the trails but permits the right khand trail to be folded against its mate.

In changing the mount from the iringto thetravelling position the gun is removed and the plunger 17 is retracted and moved to the left until the housing, carrying with v it the framel2 abuts against the hand-wheel 21. The Vright hand trail, when the customary transom V(not shown) is removed may then be folded against the left trail to form a compact unit convenient for carrying by hand or serving as a coupling to a vlimber.

The hand wheel is in a very favorable po# sition for manipulation by the gun pointer and for avoiding interference with the gun server.v f

vI claim:

1. A mount for guns including a pair of pivoted trails, couplings in the trails, a traversing screw mounted in said couplings and headed at-each end to. limit extension of the trails, alhand-wheel fixed to the screw adjacent one trail and cooperating lwith thev coupling to prevent lateral displacement of the screw with respect to said trail, Va housing freely sli'dable `on the screw, a plunger mounted in said` housing and normally engaging a thread of the screw anda pivoted gun carrying frame engaging the housing andmovabletherewith.

2. A mount for guns including a pair of pivoted trails,a traversing screw mounted in the trails and limiting their extension, a hand-Wheel fixed to the screw and arranged to prevent lateral displacement. ofthe screw gun-carrying frame engaging the housing.

and movable therewith.

'3. A mount for gunslincluding apair` of.

pivoted trails, a traversing screw mounted in the trails ,and limiting their. extension, a hand-wheel fixed to the screw and arranged to prevent lateral displacement ofthe screw with respect to one of the trails, a pivoted gun-carrying frame movablealongvthe screw Vgun supporting element and means connectand a releasable connection between said frame and screw.

4. In a gun mount7 a traversing screw, a hand-wheel for rotating the screw7 a housing freely slidable on the screw, aV plunger mounted insaid housing and normally engaging a threadk oV the screw and a. pivoted gun-carryingl frameengaging the housing and. movable therewlth.

5. In a gun mount, a. traversing screw,l ,means for. rotating the screw,ia plvoted guncarrying frameI movable along the screw and meansrfor releasably locking the frame to the screw without locking the screw against rotation.

6. In a gun mount, a traversing screw, means forrotating-'thescrem a pivoted guncarrying frame movable along the sorewand a releasable connection `between said frame and screw. V

7 In a gun mount, a traversing screw, a

ing the element to the screw for traversing the' element7 said means releasable whereby the 'element may be traversed independently of the screw.
